Note that pMg = –log[Mg2+]. What does the graph tell you about the relationship between Mg2+ concentration and ATP hydrolysis? What is the mechanism that explains the relationship between Mg2+ concentration and ATP hydrolysis?arrow_forwardThe standard free energy change for ATP hydrolysis is -7.3kcal/mol. The free energy change under typical cellular conditions is about -12kcal/mol. Why is there a difference? O The hydrolysis of ATP must be more difficult in the cellular environment O There is more ATP and less ADP in the cell O The cellular environment is anaerobic so O2 levels are reduced O The enzymes involved in the reaction are trapped in organellesarrow_forward

The fat is metabolized completely to water and carbon dioxide. 2. The energy that is released can be used entirely for ATP production. 3. Complete oxidation of 1 g of fat to water and CO2 releases 9 kcal or 37 kJ. 4. The Delta G for ATP hydrolysis is -30.5 kJ/mol. You will have to look up one more value online to answer this question, but you do not need to know anything about lipid metabolism. A) approx. 16 to 17 g of fat B) approx. 65 to 66 g of fat C) approx 22 to 23 kg of fat D) approx. 267 to 268 g of fat E) approx. 5 to 6 kg of fatarrow_forwardThe formation of ATP by ATP Synthase is part of a coupled reaction, as discussed in class. Given the information below and using what you know about ATP Synthase and the proton motive force, calculate the overall AG and determine if the coupled reaction is favorable overall. Note that you do not need to worry about intermediates like we did for the class example. ADP + Pi → ATP has a AG = 7.3 kcal/mol 2 moles of protons traveling back down their gradient across the inner mitochondrial membrane has a AG = -10.28 kcal/mol %3D O a. Overall AG = -17.58 kcal/mol, favorable overall O b. Overall AG = -2.98 kcal/mol, favorable overall %3D O c. Overall AG = 2.98 kcal/mol, unfavorable overall O d.
